Summary
[none]
Details

In the Linux kernel, the following vulnerability has been resolved:

NFS: Fix a potential NULL dereference in nfsgetclient()

None of the callers are expecting NULL returns from nfsgetclient() so this code will lead to an Oops. It's better to return an error pointer. I expect that this is dead code so hopefully no one is affected.
